Challenges in Developing the Basic Design of the KBS-3 System into a Qualified and Industrially Viable Operation - 14465

Le résumé fourni par la source

The programs for final disposal of spent nuclear fuel are similar in Sweden and Finland, and there has been extensive cooperation between the waste management organizations in the two countries over the years. This cooperation will now be deepened, aiming when possible for the same technical design. While a technically feasible reference design and layout is presented for the repositories in the two countries, detailed designs adapted to an industrialized process designed to fulfilling specific requirements on quality, cost and efficiency need still be developed. Also the repository layout needs to be adapted to the local conditions found when constructing the repository at depth. Both SKB and Posiva have developed design requirements and other conditions and presented these to the designer. However, the formulation of requirements such that they lead to designs that both meets long term safety and can be verified is not trivial and revision and harmonization between the organizations is needed. Essentially the detailed technical design need to be completed in time for the detailed design of the planned facilities in the KBS3 repository system, i.e. the encapsulation plant, the facility for buffer and backfill bentonite component production and the underground repository.
